Latoria is horseback riding when she falls and hits her head. after the accident, she has difficulty performing finely coordinated movements. latoria has most likely damaged her ____.
a. medulla oblongata
b. reticular formation
c. cerebellum
d. locus coeruleus
Final answer:
Latoria has most likely damaged her cerebellum, which is responsible for balance, coordination, movement, and motor skills. The correct answer is option C, "cerebellum."
Explanation:
Latoria is horseback riding when she falls and hits her head, and afterward has difficulty performing finely coordinated movements. Given these symptoms, Latoria has most likely damaged her cerebellum. The cerebellum is the part of the brain responsible for controlling balance, coordination, movement, and motor skills. It receives messages from muscles, tendons, joints, and structures in our ear to manage these functions. The cerebellum can make necessary changes to motor commands, as seen when a person adapts their walking movement in water. When the cerebellum does not work properly due to damage or the effects of alcohol, coordination and balance are significantly impaired.

If the sequence of nucleotide on mRNA template is AUCGUA then sequence of newly synthesized DNA strand would be?
Answer:
The correct answer will be- T A G C A T.
Explanation:
The mRNA is the messenger molecule formed by the process of transcription from the anti-sense DNA strand as a template.
The mRNA usually contains code for the synthesis of proteins but can also synthesize the DNA by the process of reverse transcription. The complementary nucleotide will bind according to the Chargaff rule which states that A will bind T or U and G will bind C.
So, if mRNA strand is- A U C G U A
DNA strand will be- T A G C A T.

Identify the two minerals shown that exhibit fracture as a dominant form of breakage
Among the properties used to identify minerals, we can mention the breaking tendency: cleavage or fracture. The two minerals shown that exhibit fracture as a dominant form of breakage are quartz and olivine.
Many properties of minerals are used to identify them, such as color, density, hardness, among others. In this case, we are talking about their breaking tendency.
How do minerals break?Minerals can cleave or fracture, which depends on how the sides separate and the formed angles.
A type of mineral breaks always in the same, and this is why the breaking tendency is useful to identify them.
CleavageThe mineral breaks in flat smooth planes.Cleavage direction and smoothness of surfaces are significant when identifying.FractureThe mineral break in irregular planes.In these minerals, there is no particular breaking direction.Image analysisAccording to this information, we can analyze the images and look for the answer.
Let us take, for instance, the potassium feldspat option. It shows flat and regular planes. So this is not a fracture, but a cleavage.
On the other side, quartz and olivine, do not seem to show any regular breaking side. The shape of these minerals is not well-defined and does not show any breaking direction.
The two minerals shown that exhibit fracture as a dominant form of breakage are quartz and olivine.

The correct sequence of parts that carry cardiac impulses is
SA node > AV node > AV bundle (bundle of HIS) > Bundle branches > Purkinje fibers.
The sinoatrial (SA) node, located in the right atrium, produces an electric impulse by contraction. This impulse travels to the atrioventricular (AV) node, located at the partition of the atria. There is a tenth of a second delay in the impulse as the AV node contracts and sends the impulse through the bundle's branches to the ventricles. The bundle branches further divide into Purkinje fibers in the ventricle walls. When the impulse reaches the Purkinje fibers, they make the ventricles walls to contract.
The correct sequence of parts that carry cardiac impulses is SA node, AV node, bundle of HIS, bundle branches, purkinje fibers, ventricular muscle cells.
Sinoatrial node: Located in the right atrium, the SA node initiates the electrical impulses that regulate the heart's rhythm.
Atrioventricular node: Located near the center of the heart, specifically in the atrial septum, the AV node receives the electrical impulses from the SA node.
Bundle of His: After passing through the AV node, the electrical signal travels down the bundle of His, a pathway composed of specialized muscle fibers.
Bundle branches: The bundle of His divides into two main branches called the right bundle branch and the left bundle branch.
Purkinje fibers: The bundle branches further divide into smaller fibers known as Purkinje fibers.
Ventricular muscle cells: The Purkinje fibers stimulate the ventricular muscle cells, causing the ventricles to contract and pump blood out of the heart.
Thus, the electrical impulses originating from the SA node are efficiently transmitted to the atria and then to the ventricles, ensuring coordinated and effective contractions of the heart.

What is the most likely consequence of open pit mining on plant life? a. a dramatic reduction in the variety of plant species b. an increase in the number of plant species c. the complete loss of plant life in the area occupied by the surface mine d. a temporary decrease in plant populations
Answer: c. the complete loss of plant life in the area occupied by the surface mine.
Open pit mining is a mining process that involves mining of earth surface, instead of underground layers. It is also, known as strip mining. It is done to extract ore and fossil fuels from the surface of earth. An open pit mining removes the subsurface soil along with vegetation growing on that surface.The mining site exhibits the mining pits, the soil in these pits changes constantly due to erosion. The soil looses it's fertility. This converts the mining site into a barren land.
Therefore, the complete loss of plant life in the area occupied by the surface mine is the most likely consequences of open pit mining on plant life.

During the process of cell division when does the nuclear membrane reform?
A. Prophase
B. Interphase
C. Telophase
D. Anaphase
Mitosis is divided into several phases, including prophase, prometaphase, metaphase, anaphase and telophase. As the intermediary phase between prophase and metaphase, prometaphase is sometimes considered part of prophase. The disintegration of the nuclear membrane into tiny vesicles signals the end of prophase and the beginning of prometaphase. When the envelope breaks down, the mitotic spindle fibers gain access to the DNA of the cell. The fibers then attach to the chromosomes at their kinetochores and begin moving to polar opposites of the cell.
The nuclear membrane re-forms in the phase of cell division known as telophase, separating the genetic material from the rest of the cell.
Explanation:The nuclear membrane re-forms during the telophase stage of cell division. In this phase, the chromatin that had condensed into chromosomes begins to relax and the nuclear envelope forms around each set of chromosomes to separate the nuclear DNA from the cytoplasm. This maintains a barrier that regulates the flow of substances into and out of the nucleus. Thus, option C: Telophase is the correct choice.

The ________ division of the nervous system carries motor commands to muscles and glands.
The answer is efferent division. The nervous system acts as an input-output system. The afferent nervous system conveys signals to the brain following a stimulus. After processing of the information, the brain sends out a signal in response. This response is carried by the efferent nerve to the requisite organ involved in the response.
Final answer:
The motor division of the nervous system, part of the peripheral nervous system, sends motor commands to muscles and glands, divided into the somatic and autonomic nervous systems for controlling voluntary and involuntary actions.
Explanation:
The motor division of the nervous system carries motor commands to muscles and glands. This part of the nervous system is crucial for stimulating muscles to contract and glands to secrete hormones. It is part of the peripheral nervous system (PNS) and is further divided into two main systems: the somatic nervous system and the autonomic nervous system.
The somatic nervous system controls voluntary movements by acting on skeletal muscles, whereas the autonomic nervous system regulates involuntary activities, influencing glands, smooth muscles, and cardiac muscles. It includes further subdivisions like the sympathetic and parasympathetic systems, which are responsible for the body's fight-or-flight response and rest-and-digest activities, respectively.

1. Which of the following is needed for cellular respiration to occur? (2 points)
Sodium
Oxygen
Water
Nitrogen
2. Which of the following correctly compares fermentation and cellular respiration? (2 points)
Both provide ATP molecules, but only fermentation occurs when oxygen is present.
Both result in substantial ATP molecules and lactic acid production.
Cellular respiration produces more ATP molecules than fermentation.
Cellular respiration provides ATP molecules at a slower rate than fermentation.
3. What ultimately happens to the light energy captured during photosynthesis? (2 points)
It is used to produce glucose molecules.
It is turned into more chlorophyll for the plant.
It is used to release the energy from H2O.
It is put into ATP molecules for long-term storage.
Answer:
1. The correct answer would be oxygen.
Oxygen is used as the terminal electron acceptor in cellular respiration. It results in the production of water (byproduct) from oxygen.
2. The correct answer is the third option, that is, Cellular respiration produces more ATP molecules than fermentation.
Fermentation takes place in absence of oxygen which results in the production of lactic acid (or ethanol). In absence of oxygen, glucose does not break down completely due to which less number of ATP is produced.
Fermentation only produces 2 ATP molecules per glucose molecule. In comparison, cellular respiration produces 36-38 ATP per glucose molecule.
3. The correct answer is option third.
The light energy is used to phtolysis of water which releases oxygen and high energy electrons. These electrons are then used to produce NADPH and ATP. These NADPH and ATP are then used in dark phase to fix carbon into glucose.
